Abstract
A method of wrapping plant materials for storage by wrapping the plant materials with a food wrapping material obtained by stretching a styrene-based polymer film with mainly syndiotactic configuration. The wrapping material is transparent, has gloss and is excellent in physical properties such as gas permeability and heat resistance making it very useful in the method for wrapping material such as vegetables and fruits requiring permeation and diffusion of gases such as oxygen and carbon dioxide.
